There is a strong evidence that recent data on ${{\mathit B}}$ $\rightarrow$ ${{\mathit D}}{{\mathit \pi}}{{\mathit \pi}}$ (AAIJ 2015Y, AAIJ 2016AH) and ${{\mathit B}}$ $\rightarrow$ ${{\mathit D}}{{\mathit \pi}}{{\mathit K}}$ (AAIJ 2014BH, AAIJ 2015V, AAIJ 2015X) call for two poles in the scalar $\mathit I = 1/2$ ${{\mathit \pi}}{{\mathit D}}$ amplitude in this mass range. The data are consistent with a lower pole at ($2105$ ${}^{+6}_{-8}$) $−$ ${\mit i}(102$ ${}^{+10}_{-11}$) MeV and a higher pole at ($2451$ ${}^{+35}_{-26})−$ ${\mit i}(134$ ${}^{+7}_{-8}$) MeV (DU 2018A, DU 2019 , DU 2021 ).
